Virtual Reality for the Elderly | Evolving Science - Computer Science & Technology

"We all want the best for our families, but sometimes we have to make a hard decision and opt for assisted living for our elderly" summarizes Paul Beatty, PhD.

This can stem from a gradual decline in health, difficulties in performing menial tasks, loss of cognitive functions requiring supervision, or general depression from being isolated from others. We choose assisted living communities for peace of mind; that our loved ones are being cared for and enjoying the best quality of life.

However, this isn’t always the case. Some complaints about nursing homes are either boredom or lack of physical activity. Though many homes offer fitness facilities or programs, most residents don’t raise their heart rates enough. To address this, a research team from Aalborg University would like to introduce virtual reality technology to increase senior citizen activities. The goal for the team is to change exercise from chore to a pleasing digital experience.

Technology 
Generally, there is minimal motivation to get up and exercise. For one, it can be painful and secondly, it can be uninteresting to stare at a blank wall. A study was conducted at a Copenhagen nursing home with 21 elderly residents. Large screens were mounted on the wall and the residents were encouraged to ride stationary bikes through projected landscapes. The bikes were linked to the screen so the landscape would reflect their speed. All the seniors had a positive experience.

The researchers want to expand the experience and equipped the subjects with virtual reality (VR) goggles. The small screens in front of the eyes project a landscape based on the direction the subject is looking. This includes mountains, birds, buildings, trees, and the sky. The mundane task of riding an exercise bike in a fitness room was transformed into a vivid experience. The desire to use the exercise bikes rose significantly.

Other Benefits 
There are other benefits to using VR than just raising heart rates. VR has been used as a behavior intervention in pain management. Researchers at Duke University, point out that pain requires conscious attention, but VR-based distractions leave the subject to maneuver in ways that were otherwise prohibitive. The fear of pain associated with movements is avoided while in VR.

Much like Duke University, a team from the University of Montreal is exploring cognitive-behavioral therapy to address anxiety with VR. It’s thought that 25% of people age 65+ experience varying degrees of anxiety. In VR, subjects are exposed to fear triggers in a controlled environment where they can be confronted to the point that the anxiousness is diminished. Going a step further, VR is now being applied in cognitive rehabilitation for those affect by mild impairments, like early-stage dementia.
